Bash - How to get http response body and status code?

Question

I am trying below code to get response body and status:

read -ra result <<< $(curl -i --insecure \
    -H "Accept: application/json" \
    -H "Content-Type:application/json" \
    -X POST --data "$configData" $openingNode"/voice/v1/updateWithPh")
status=${result[1]}
response=${result[@]}
echo $status

Problem here is -

I get both status code and response Body correctly. But when I create a bash function and send it as an argument, the response body changes to "HTTP/1.1" in the function as shown below.

echo $(validateUpdate $configData $response)

Code for the function -

function validateUpdate(){
   echo $1
   echo $2
}

$2 prints as "HTTP/1.1"

What is the reason? How to rectify this issue?

Perhaps you have a newline in `$configData`. Can you try to quote your vars: `echo $(validateUpdate "$configData" "$response")` — Walter A, Feb 19 '18 at 22:42

You need to enclose your variables in double quotes to prevent bash splitting it into separate tokens.

Try

echo $(validateUpdate "$configData" "$response")

or even better (echo is useless as @tripleee points out; furthermore curly braces improves readability):

validateUpdate "${configData}" "${response}"

use same thing inside of your function

echo "$2"

`echo $(command)` is usually better written `command` unless you specifically *require* the shell to perform whitespace tokenization and wildcard expansion on the output from `command` before printing it.

Use this:

RESPONSE=$(curl --request POST \
  --url $URL \
  -w "\n%{http_code}" \
  -s)


RESPONSE_CODE=$(tail -n1 <<< "$RESPONSE")
RESPONSE_BODY=$(sed '$ d' <<< "$RESPONSE")

echo "Response code = ${RESPONSE_CODE}"
echo "Response body = ${RESPONSE_BODY}"
